[pete.triumph]

I changed the stock size mezt 150/80 front tyre ,fitted pirelli night dragon front tyre 140/75 took some measurements of both tyres the stock 150/80 measured 140/88 new 140/75 size measured 138/76 . the measurements done on rim and inflated the new tyre is 13 mm lower , but bike is much more stable now at high speed and cornering as well ,i also lower the folk tube a little so to keep cornering clearance

YOULL find you dont have to lean the bike as much to change directions and the bike will feel much lighter

Keep us advised on that Night Dragon.
Is yours the 140/75R17 or the 140/80R17?
I find it very curious that the 140/75R17 ($132 at Rocky Mountain ATV) is V speed rated while the 140/80R17 ($154 at Rocky Mountain ATV) is only H speed rated
yet the 80 costs more money???
I currently run the Avon 140/75R17 ($160 at Rocky Mountain ATV), but thinking I may try one of these Night Dragons just for $hits & giggles.
I like the Avon plenty, but ALWAYS on the look for something little better.

It's the 140/75 I wanted v rated

It really shouldn't be more stable if you make the front end lower, that should change the rake in the direction of less stable but more nimble.

Though it's possible the Pirelli is superior, lord knows my R3T became 100% better with v-rated Avons.

I slid the folks down 10 mm so to raise the hieght with the lower profile tyre so now it's only 2 or 3 mm lower than stock
